Fires tipped to burn for 'up to a week'

The Country Fire Service (CFS) says a series of fires on South Australia's upper Eyre Peninsula and the west coast will probably burn for several days, possibly up to a week.

The fires were started by weekend lightning strikes, with significant smoke yesterday causing some public concern further north at centres including Coober Pedy and Tarcoola.

CFS regional prevention officer George Kozminski says it is likely the fires will eventually blow back on themselves.

"There's nothing we can do, most of these fires will just keep going, the weather will influence their behaviour," he said.

"With the current weather conditions we've got they don't pose any threat to life or property and hopefully with the weather forecast over the week that might take care of it.

"They'll trickle around there for a couple of days, maybe even up to a week, it's all dependent on what the weather is going to do - as soon as the weather turns around it will more than likely blow a lot of those fires back on themselves."
